Like Russ said, they're both (the fuel pump relay under the dash and 
the main FI power relay under the back seat) the same.

Only the 68-9 CSV design included a relay, and that system was so 
complicated that I'd never recommend that anyone use it. On the later 
systems I've never seen a CSV CAUSE a problem, but I HAVE seen 
misunderstandings and misassembly cause CSV problems.

The late CSV system is quite simple and really doesn't cause any 
trouble if it is hooked up right. Kind of like blaming the coil if 
you connect it with the polarity wrong. We've also seen a lot of 
people express concern that their CSV is causing problems, but I 
think those problems always turn out to be something else (like the 
worn out voltage regulator problem, which makes the engine run rich.)

OTOH, I'm not sure that the CSV system actually serves any useful 
purpose. Most of our cars seem to work just fine with them disabled.
